Method Details

newInstance

public static DnsRDataA newInstance(byte[] rawData,
 int offset,
 int length)
                             throws IllegalRawDataException

A static factory method. This method validates the arguments by ByteArrays.validateBounds(byte[], int, int), which may throw exceptions undocumented here.

Parameters:

rawData - rawData

offset - offset

length - length

Returns:

a new DnsRDataA object.

Throws:

IllegalRawDataException - if parsing the raw data fails.

getAddress

public Inet4Address getAddress()

Returns:

address

isAddressPlainText

public boolean isAddressPlainText()

Returns:

true if the ADDRESS field is a plain text; false otherwise.

length

public int length()

Specified by:

length in interface DnsResourceRecord.DnsRData

Returns:

length

getRawData

public byte[] getRawData()

Specified by:

getRawData in interface DnsResourceRecord.DnsRData

Returns:

raw data

getBuilder

public DnsRDataA.Builder getBuilder()

Returns:

a new Builder object populated with this object's fields.

toString

public String toString()

Overrides:

toString in class Object

toString

public String toString(String indent)

Specified by:

toString in interface DnsResourceRecord.DnsRData

Parameters:

indent - indent

Returns:

String representation of this object.

toString

public String toString(String indent,
 byte[] headerRawData)

Specified by:

toString in interface DnsResourceRecord.DnsRData

Parameters:

indent - indent

headerRawData - the raw data of the DNS header including this RDATA.
